5. Determine βDC, IB, IE, аnd IC in the circuit belоw with αDC = 0.69. 6. Determine the оutput vоltаge for the аmplifier from the circuit below with the following characteristics: βDC = 80, βac = 120, re’= 8.5Ω, VCC = 30 V, and Vin = 1.50 mVrms. 7. In the common-source amplifier circuit below (IDSS = 15 mA, VGS(off) = -4 V), a 3.5 kΩ resistor is connected in parallel with the load resistor. Determine the voltage gain. 8. A common-gate amplifier has a gm = 3000 μS and Rd = 2.7 kΩ. Determine: a. the gain, b. the Rin(source). 9. An amplifier has the following low critical frequencies: 20 kHz, 44 kHz, and 112 kHz. The fT = 150 MHz and the mid-range gain is 28. Determine: a. the bandwidth, b. the upper critical frequency. 10. In a step-response of an amplifier the rising time was 15 μs and the falling time was 1.2 ms. Determine the bandwidth of the amplifier.
